What Car?’s technicians drive new cars every week to capture our True MPG fuel economy data. Unlike official Government figures generated by a laboratory test, the numbers we publish are gained from real-world conditions.

This week we’re looking at the most economical convertibles and cabriolets we’ve tested so far. If you want an impressive drop-top that should do more than 35mpg in real-world driving, these ten models should be on your shortlist

The Volkswagen Beetle Cabriolet is not the most entertaining car to drive, but its styling will more than justify any handling niggles for most owners. Otherwise, it’s a comfortable, refined place to be. Don’t expect to use it as a full-time four-seater, though, because the rear seats are cramped.

The latest Audi TT is great to drive and thanks to a practical interior is also surprisingly easy to live with. The 1.8-litre petrol engine recommended here is the entry-level option, but it doesn't feel underpowered and it's happy to be revved hard. There aren't any rear seats in the TT, and not much room to store belongings either, so if you're heading for a weekend away it's best to pack light.

Small convertibles don’t come much more stylish than the DS3 Cabriolet, although the retractable fabric roof is more of a big sunroof than a full drop-top. Still, it can be put back in place at up to 74mph. The DS3 is good to drive, with this 1.6 VTi engine being the best match for leisurely motoring.

As small convertible cars go, the Mini Cooper Convertible is one of the most sought-after models around. It's fun to drive and is powered by a range of strong and flexible engines, and the four-seat cabin is a nice place to be. There's also plenty of tech inside, including BMW's excellent iDrive infotainment system. Be wary, though, because with the roof up rear visibility is hampered, and space in the rear is tight.
